There's no doubt that Steve Irwin would be proud of how his daughter has consistently honored him during her run on "Dancing With the Stars" this season.
The photo was actually a surprise to Irwin and was orchestrated by Hough. There wasn't a dry eye in the ballroom and Irwin hugged Hough after the image popped up on the screen.
Irwin and Hough led the way in part 1 of the "DWTS" finale, scoring perfect marks for their two rounds of dance.
Around the same time, Irwin, herself, took to Twitter to post a throwback photo of the family.
"The last photo as a family, before I had to wave goodbye to my hero, for the last time. Dad, I love you," she wrote.

Irwin died almost a decade ago when a stingray struck him while he was snorkeling. He was 44.
